I'm sure Miles would say he has made some mistakes, but what I've learned about life is you do everything right and sometimes things still don't go your way. Doing things the right way is no garantee of success but not doing things the right way almost always garentees failure.
Something like "your father in law came and talked to me? - tell him to get over it". I think Taylor is in the wrong here, but Miles put Tai in an awkward spot bringing it up in front of a room full of reporters and cameras.
